About the stuttering/performance issues...

[MikeyD]

Porcelain It's your PC, I don't get any stutters like you are complaining, could be CPU problems or bad config
Either way I doubt theres anything anybody here can do for you

Resxt I'm saving up to build a high end PC anyway, so back to BO2 it is.

One more thing though, why does Pluto only utilize 860mb of memory compared to Steam using 1200+?

[Resxt]

Porcelain because it's more optimized.
Also, using more power does not mean giving more performance. Using all your RAM wouldn't increase your FPS

Resxt The fact that bo1 is stuttering on my pc when i have a gtx 1660 ti which can run most games at 60+ is ridiculous

ScorpionR452 contact Treyarch about it

I didnt saw any mention for a fps cap? You do know that this is a 15 year old game and the engine was not designed to handle so many frames and it just bottlenecks. Just cap the fps at 250 if you havent.

Yeah anything past 300 on the cod games gets pretty wacky.. getting stuck on small ledges you can walk up, to literally climbing props on bo2

[Resxt]

@FomroMadia above 200 for BO2. Most likely the same for others

I get stuttering on MW3 on certain maps whenever I add bots (bot warfare mod). With no bots no stuttering. Also get stuttering on spec ops
